To all whom it may concern:

Be it known that I, Lonwro STEPHANY, Sn, a citizen of the United States,residing at Philadelphia, in the State of Pennsylvania, have invented acertain new and useful lgiproved Non-Qkidding Device, of which tfollowing is a specification.

his inventionhas for an object to provide a simple, efficient andcomparatively inexpensive non-skidding device adapted for use uponmotor-car wheels, so arranged and constructed that the cross-chainsupporting means of the device are detachably secured to the spokes of awheel but are calculated to remain permanently in place thereon,cross-chains being adapted to be detachably secured to the brackets butnormally carrie in the tool .box oft-he motor-car, whereby a light,easily carried and readily mountable non-skidding device is provided,the parts of which may be attached and detached without the employmentof tools. Other and further .objects will appear hereinafter.

The invention consists of the improvements hereinafter described andfinally claimed.

.The nature, characteristic features and scope of the invention will bemore fully understood from the following description in connection withthe accompanying drawings forming part hereof, and in which;

Figure 1 is a fragmentary view in side elevation of a motor car wheelillustrating the application thereto of the non-skidding embodying theinvention, 2 is a. similar view 111 transverse secdevice a Fig. tion,

For the purpose of illustrating myinvention 1 have shown in the accompanying drawings forms thereof whichare at present preferred by me, since the same have been found inpractice to give satisfactory and reliable results, although it is to beunderstood that the various instrumentalities of which be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown and described.

Application filed July 15, 1918. Serial No. 245,092.

the invention said means comprising brackcts clamped with respect to thespokes 11 of a motor-ear wheel. The cross-chains which may be of anydesired form are designated 12. Referring now more particularly to Figs.1 to 3 inclusive, each bracket comprises a clamp 13 detachably securedto :1 spoke 11 as at 14 but calculated to remain permanently in positionthereon. One part of said clamp is provided with a boss 15 the face ofwhich is serrated thereacross as at 16. Fixed to the-serrated face ofsaid boss is a screw-threaded stud 17 for the accommodation of athumb-nut 18. A slide 19, the inner face of which is serrated, isadapted to coact with respect to the serrated face of the boss 15, saidslide being slotted as at 20 to accommodate the stud 17. Thus the slidemay be shifted toward or away from the wheel center, the serrated facesof the boss and slide co-acting to positively hold the slide ll; placeas secured by means of the thumb-nut 18. In this fashion a. nicety ofadjustment may be secured as well as positive interlock of parts. thatpart oi the clamp opposite the part boss 15 are each provided with afixed hook 21. The free end of each book is provided with a reverselybent portion twisted to form a narrow mouth to receive a link of across-chain 12. Such construction forms what may be termed reentranthooks which serve to securely hold in place a cross-chain during thehard usage to which, a non-skidding device is put.

In practice the clamps-13 together with their complemental Slides 19 arefitted-to place upon the spokes 11 of a vehicle wheel, preferably forpermanent fixture thereto. The'cross-chains 12 may be stored in thevehicle tool-box. When occasion arises for the use of the chains thesamemay be readily fitted to the rentrant hooks above described. In thisconnection it may be remarked that by adjust-lug theslides 19 withrespect to the bosses 15 said chains may be snugly caused to engage overa tire. This is important when the chains have become worn and thin andwhen the tires are partially deflated.

In the modified form shown in Figs. 4 and 5 the serrated boss and slidehave been omitted from the clamp which is hinged as at 22, see Fig. 5.The reentrant hooks are of the same construction as above described.

It will now be apparent that I have de- The slide 19 and I have in thepresent instance shown and described the preferred embodiment thereofwhich has been' found in practice -to give satisfactory and reliableresults, it is to be understood that the same is susceptible ofmodification in various particulars without departing from the spirit orscope of the invention or sacrificing any of its advantages.

What I claim is: 1

1. A non-skidding device comprising a bracket adapted to engage aroundthe spoke of a vehicle wheel'said bracket being provided with a serratedportion upon one side and with a re'e'ntrant hook upon its other side,means for clamping said bracket to place, a slide serrated to coac-twith said serrated bracket, which slide is also provided with areentrant hook, means for clamping said slide in adjusted positions anda crosschain removably connected at its ends to said reentrant hooks.

2. A non-skidding device comprising a bracket adapted to engage aroundthe. spoke of a vehicle wheel said bracket being provided with aserrated face upon one side and with a reentrant hook upon its otherside; a screw-threaded stem extended from said serrated face, means forclamping said bracket to place, a slide serrated to co-act with theserrated portion of said bracket,

which slide is slotted to accommodate said stem and is provided with areentrant hook, means for engaging said threaded stem to clamp the slidein adjusted positions and a' cross-chain removably connected at its endsto saidreentrant hooks' 3. A non-skidding device comprising a bracketadapted to engage around the spoke of a vehicle wheel said bracket beingprovided with a serrated portion upon one side and a hook upon its otherside, means for clamping said bracket to place, avslide serrated toco-act with said serrated bracket,

, vided with a boss upon one side thereof having a serrated face and,with a hook-upon its other side, a'screw-threaded stem extende'd fromsaid serrated face, means for clamping said bracket to place, [a slideserrated to co-act with said serrated boss which slide is slotted toaccommodate said stud and is provided with a hook, a thumb-nut forengaging said stud to clamp said slidein, ads.

just/ed positions and a cross-chain removably connected at its endstosaid hooks' In testimony whereof I have hereunto signed my name.
